Definitions
- This invention relates to an orientation device.
- the invention relates to improvements in adjustable, clampable, orientation devices for mounting equipment including, particularly but not exclusively , speakers, microphone stands, slide projectors and the like.
- the inventors of the invention to be described hereinafter looked at various existing devices which provide swivel links/orientation devices which they believed might be suitable for use in orienting and aligning slide projectors and the like.
- the devices which provided swivelling with clamping/locking had good locking capabilities, they could not be finely adjusted while being partially clamped. In other devices with good adjusting properties the locking was insufficiently strong and reliable.
- Many of the existing devices were also over-complicated and in some cases correspondingly expensive due to their providing movement and clamping about three orthogonal axes.
- a typical swivel mechanism utilises one axle per axis, requiring one locking mechanism per axis such as in a typical camera tripod, and while this system is functional, it requires adjustment of three different clamps for adjustment in three different axes.
- Another prior art device is a theatre light mounting. That device comprises a spherical member coated with a deformable soft plastic. The member is fitted into a concave mating socket which has truncated spikes protruding inwards. When the device is clamped, the spikes are pressed into the plastic. This device holds its orientation well. However, the plastic retains the spike depressions for a long time and this makes the device unsuitable for quick re-alignment. Also, it is difficult to make slight adjustments with this device.
- an adjustable orientation device including:- a rigid part-spherical bearing surface; a sleeve made of a hard, non-visco-elastic material, the sleeve defining an inner surface which is part-spherical and is configured to receive the part-spherical bearing surface, having substantially the same radius of curvature as the same, the sleeve defining at least one gap; and means for adjusting the size of that gap the arrangement being such that when the gap is relatively wide the sleeve can be moved freely over the spherical surface, the gap being arranged to be narrowed by the means for adjusting the size of the gap and held by the means for adjusting the size of the gap, such that frictional engagement between the sleeve and the bearing surface retains the sleeve and surface in a fixed orientation.
- the preferred bearing surface is defined by a sphere with a large central bore extending from one pole of the sphere to the opposite pole to define a cylindrical bore suitable for receiving a shank.
- a particularly simple method of manufacturing an orientation device embodying the present invention is by customising an existing spherical bushing.
- Spherical bushings are made be a number of manufacturers including IKO Nippon Thomson Co., Ltd of Japan.
- a bushing consists of two parts: a ball with a large hole through it for a shank, sitting in a sleeve which is machined to the contour of the ball.
- the sleeve has an axial split, to enable the ball to be inserted in the sleeve which is closed in use when the bushing is assembled. If material around the split is removed to widen the split to define a gap, the sleeve can be compressed until the ball cannot be moved any more.
- an adjustable link, or orientation device which, when fitted to a support, allows adjustment of the orientation of the equipment mounted to it.
- One element say the spherical surface is connected directly or indirectly to the equipment, the other element being the sleeve is attached to the surface or object to which the equipment is to be mounted.
- This link has associated with it methods of clamping so that the equipment may be held at any orientation within the scope of operation of the support. Clamping may be of varying degrees to provide effects which range from light holding to rigid locking. In the case of equipment which is re-orientated often by hand, by careful adjustment, it is possible to provide just enough resistance to hold the equipment at a suitable orientation and also readily allow movement when subjected to any additional force.
- clamping is obtained hydraulically by means of cylindrical bore having a groove or channel extending around the inner circumference of the bore and a sleeve or the like covering the channel/groove such that application of pressure to a hydraulic medium in the groove causes the sleeve to bow inwards to clamp a cylindrical object, such as the sleeve or possibly an axle, in the bore.
- Typical uses for the present invention include mounting speakers, in boom microphones, and slide projectors; mounting overhead, video and film projectors; mounting lights, video, still and film cameras; mounting optical, electro magnetic and acoustic transmitters and receivers; mounting viewing equipment such as magnifiers, binoculars, telescopes; mounting display equipment such as placard, card and label holders; signs, mirrors, and in tool holding and work holding equipment e.g. swivel vices.
- the invention provides a plate to which the projector can be secured, a lens retention device, such as a ring extending around the lens, the ring being secured to the plate, and an orientation device of the present invention, one element of which is secured to the plate and the other element being securable to a table bench, ceiling or other surface on or to which the projector is to be mounted
- the slide projectors are mounted in a room at the back of a lecture theatre where the projector projects through a window to the screen at the front of the theatre.
- the projection lamps sometimes need to be replaced during a slide show and are therefore in many projectors hold replacement lamps in a drawer like cartridge which pulls out from the back of the projector.
- access to this module requires turning the projector and this means that the projector has to be re-aligned afterwards.
- the clamping means includes means for allowing the projector and mounting assembly to turn in one direction away from a project position, a stop means which set at the project position and biasing means to bias the projector towards the stop means.

- Figure 3 shows the bushing of Figure 2 fitted into first clamping mechanisms with a stem added
- Figure 4 shows a sectional view of a second clamping mechanism using a screw and two opposite contact points
- Figure 5 shows a further embodiment of a clamping mechanism

- Figure 7 is a schematic drawing of a projector mounted on the projector mount of Figure 6;
- Figure 8 shows a further embodiment of a clamping mechanism
- Figure 9 is a schematic drawing of a projector mounted on a second embodiment of a projector mount
- Figure 10 shows a speaker on a mounting
- Figure 11 is an enlarged view of the mounting of Figure 10.
- Figure 1 shows a section through a typical spherical bushing 10 comprising an inner ring 12 whose outer surface 14 is spherical and an outer ring, or sleeve, 16, whose inner surface 18 is also part- spherical and defines the surface of a spherical segment.
- the inner ring is free to rotate about its central axis 12A.
- the ring 12 is also free to turn inside the sleeve 16 so that its axis 12A turns relative to the axis 16A of the sleeve.
- Such bushings are well known in the art and are often used in heavy machinery such as cranes bulldozers and the like and are particularly used to mount ends of large hydraulic cylinders, with a shank being mounted in the inner ring.
- Such bushings are typically manufactured in a hard steel material such as high carbon chromium bearing steel, and the surfaces 14, 18 of the bushing are often coated to improve wear, smoothness, decrease friction etc.
- the bearing surfaces are phosphate-treated and coated with molybdenum disulphide.
- the inner ring is inserted in the sleeve by means of a split in the sleeve which is opened in the assembly process to insert the inner ring and which is otherwise completely closed in the finished bushing.
- Figure 2 shows a first embodiment of the present invention, generally indicated at 20, which includes an inner ring 12 identical to the ring shown in Figure 1 and whose outer ring, or sleeve, 22 is similar to the sleeve shown in Figure 1 but in which material on one side of the split present in the sleeve has been removed to define a gap 24. If the outer ring 22 is now compressed to narrow the gap it will hold the inner ring 12, firmly.
- Figure 3 shows the device 20 incorporated in a clamping means 26 for compressing the outer ring 22 of the device.
- the device includes a further ring, or outer clamping ring 28 which is disposed around sleeve 22 which defines a gap 30 which can be closed to compress the outer clamping ring 28, and hence compress sleeve 22, by means of a screw clamp mechanism, generally indicated at 32.
- the outer clamping ring is fixed to or integral with a collar 34 which is in turn attached around a protrusion 36 at the top of a stem or pillar 38.
- a further shank or rod 40 is mounted in the inner ring 12.
- the present invention provides, an adjustable link, or orientation device, which, allows adjustment of the orientation of the rod 40 relative to stem 38.
- rod 40 or stem 38 will have equipment mounted to it or indirectly bear such equipment so that the adjustment allows the orientation of the equipment to be altered.
- the equipment may be held at any orientation within the scope of operation of the clamping means/support 32. Clamping may be of varying degrees to provide effects which range from light holding to rigid locking.
- the clamping device is able by careful adjustment of the screw clamp to provide just enough friction resistance between outer surface 14 and the inner surface 18 of the sleeve to hold the equipment at a suitable orientation and also readily allow movement when subjected an additional force.
- the device can be firmly clamped in place by tightening the screw clamp 32. Importantly, when the additional tightening is carried out, the orientation of the components of the device will not change.
- the materials must have suitable properties.
- the materials must be hard.
- the sleeve material at least must be non-visco- elastic, ie it must not creep, or deform plastically under stress under the loads applied. Elastomers such as rubber, and soft easily deformable plastics are unsuitable.
- the materials should preferably have a high modulus of elasticity, at least 50000psi, and preferably lOOOOOpsi or more. Any deformation of the sleeve under the loads applied should be in the region where the material vised behaves substantially elastically.
- Figure 4 shows a cross section through a similar device to that shown in Figure 3 but in which an alternative clamping mechanism is utilised.
- the sleeve is held in a collar 50, which extends around the outer surface of the sleeve but defines an arcuate space 52 which extends around the outside of the sleeve 22, either side of the gap 24.
- the two ends of the space 52 define contact points.
- a block 56 is attached to the opposite side of the collar to the gap and a threaded hole 58 extends through that block and the collar.
- a correspondingly threaded rod 54, defining a handle 54A is located in the hole 58.
- clamping is achieved by turning the handle to cause the end 60 of the rod to impinge on the area 62 of the sleeve 22 opposite to the gap 24 to deform the sleeve and thus cause it to lock or clamp the inner ring, not illustrated in Figure 4.
- the contact points help to ensure that the clamping is provided on the sides of the inner ring at 120° to the end 60 of the rod.
- Figure 5 shows a further embodiment 70 which is very similar to that shown in Figure 3 however as illustrated the outer clamping ring is not used and the screw clamp 72 is mounted in blocks 74 and 76 which are attached directly to the sleeve which acts as a structural element and transmits loads to the stem 38.
- Figure 6 shows a schematic drawing of a device for mounting a slide projector utilising the principals of the present invention.
- a pillar 38 is attached to a mounting plate 100. Attached to this pillar is a collar 34 and sleeve 22 which encircles an inner ring 12 which is mounted on a shank or rod 40 in an assembly similar to that shown in Figure 5.
- a cam operated tensioning device indicated at 102 acts on the clamping blocks 74 and 76 through a stalk 104.
- a plate 106 is attached to shank 40.
- a saddle 108 through which passes a rope or rod 110 which has an end 112 enlarged so that it cannot pass through the saddle.
- the other end of rope or rod 110 is attached to a lens lock indicated at 114 comprising a split ring similar to a hose clamp which encircles a lens 122, shown in Figure 7, to prevent unauthorised removal of the lens.
- a screw 116 or other more secure device clamps the two ends of the split ring together.
- the stalk 104 is of a length that brings the tensioning device 102 to the side of the projector for ease of use. Where this fixture is used to attach other projectors, such as video/data projectors to the underside of a ceiling or pole, the stalk may be flexible and long enough to bring the tensioning device to below the projector for ease of access.
- Figure 7 shows a schematic drawing of a projector 120 mounted to plate 106 of the assembly shown in Figure 6 with the lens 122 clamped in the lens lock 114 and the mounting plate 100 attached to a table, indicated at 124.
- Orientation with the screen is achieved by rotating the projector sideways and tilting the projector using the built in screw adjustable feet 126 the orientation device is clamped after all adjustments are made.
- Typical uses for the present invention include mounting overhead, video and film projectors; mounting speaker microphones, lights, video, still and film cameras; mounting optical, electro magnetic and acoustic transmitters and receivers; mounting viewing equipment such as magnifiers, binoculars, telescopes; mounting display equipment such as placard, card and label holders; signs, mirrors, and in tool holding and work holding equipment e.g. swivel vices.
- the swivel locks may be compressed using electro-motive, hydraulic (liquid or gas) force or by screw, cam, joggle, or lever action.
- the clamping mechanism may take the form of a split collet with the spherical inner member held in a matching shape formed within the fingers of the collet.
- the gap 24 in the sleeve 22 is made by removing material, the sleeve could be manufactured with a gap, or gaps.
- the sleeve has a single gap
- a sleeve having more than one gap could be used in appropriate housings.
- the sleeve can be cut into segments, and mounted a partly slotted housing with a conic outer wall. Compressing is done by pulling or pushing this into a corresponding cone, much like collets used in metal working.
- the sleeve could be replaced because the contour of the ball could be machined into such a collet.
- Figure 8 shows a sectional view through a further device 128 incorporating an alternative method of adjusting the size of the gap in the outer ring 22 of an orientation device of type already described and shown in Figure 2, at 20.
- the device 128 could also be used in many of the mechanisms described above.
- the device 128 includes a generally annular housing 130, which defines a central cylindrical bore generally indicated at 132.
- the bore defines an annular groove 134 which extends circumferentially around the inner surface of the bore.
- the bore is sealed by a sleeve 136, and an hydraulic medium in the bore can be pressurised which causes the sleeve 136 to bulge inwards which will compress the outer ring 22 which is disposed in the bore compressing, it which will narrow the gap 24 thereby causing the outer ring to clamp against the inner ring.
- annular groove 138 which extends around the outside of the outer ring 22.
- the sleeve 136 When pressure is applied to the hydraulic medium in the groove 134 the sleeve 136 is pressed against the external surface of the outer ring 22 and the sleeve 136 will distort and become pressed into the groove 138. If the sleeve is made from material which will retain its shape after distortion, the shape of the annular groove 138 becomes reflected in the sleeve preventing the device 20 from being removed from the housing after the hydraulic pressure has been removed. In the embodiment described above, the sleeve is bonded to the housing 130 to seal the bore 134.
- the sleeve could be made as part of the housing 130.
- the housing 30 with sleeve 136 can be placed directly around a shaft and when pressure is applied movement in the shaft relative to the housing could be controlled, slowed or stopped.
- Various materials could be used in the sleeve or in coatings applied to it which could vary its properties.
- the bore and sleeve may take the form of shapes other than cylindrical.
- the bore and shaft may be square, splined, or oval.
- the sleeve will bulge and press against the shaft.
- This method may also be used on an external surface, where the sleeve form part of the outer surface of a shaft. Again the bore, shaft and sleeve do not need to be cylindrical.
- Some uses for these devices are as dampers on swing arms of vehicles, bicycles and other suspension arms where the axle around which the swing arm rotates is held in a housing as described above and by applying hydraulic pressure to the housing where the sleeve includes or acts on a friction surface, the action of the swing arm is controlled. By varying the hydraulic pressure the swing arm damping could be modified to suit altering conditions.
- This device could replace or augment traditional shock absorbers.
- the method can be used to replace the mechanical components of a drum brake.
- Figure 9 shows a variation on the projector mount illustrated in Figures 6 and 7, which allows a slide projector to be rotated in order to access a replacement lamp housed in a lamp module of the projector.
- slide projectors are mounted in a room at the back of a lecture theatre and the projector projects a beam light through a window to a screen at the front of the theatre.
- slide projectors are merely mounted against the back of the theatre.
- the projector lamp will blow and require replacement and many projectors thus include a drawer, which pulls out from the back of the projector and in which replacement lamps are usually placed in the event that a projection lamp will blow during a slide show.
- access to the lamp module requires one to turn the projector and this means that the projector has to be realigned afterwards.
- Figure 9 shows a variation of the projector mount shown in Figures 6 and 7 which allows the projector to rotate through sufficient of an arc to gain access to the lamp module and then allow the projector to return to the project position without the need for careful adjustment.
- two arms 150 project from the collar 34 and the ends of those arms 150A define a circular plate on which the adjustable feet 126 of the projector sit.
- a pin 152 is fitted to the pillar 38 and this is supported by a collar 156.
- the collar defines a ramp or cam fit surface 154 on which the pin travels when the projector is turned about the axis of the pillar (in the direction of arrow A) to allow access to the rear of the projector and the lamp draw.
- FIG. 10 shows a speaker 200 fixed to a mounting, generally indicated 210 embodying the present invention.
- the mounting is fixed to one of a support rod 212.
- the mounting 210 incorporates a orientation device embodying the present invention which can be used to adjust the orientation of the speaker in three dimensions.
- the other end of the rod may be fixed or may also incorporate an orientation device embodying the present invention.
- the split sleeve 28 is enclosed in an outer ring or outer sleeve 228.
- the threaded clamp for tightening the sleeve 228 around the bore 12 is not shown for clarity.
- a rod 40 passes through the centre of the spherical bearing 12.
- the ends of the rod are fixed to two metal plates 230, 232 which in turn are fixed to a further plate oriented perpendicular to the metal plates 230, 232 which can be fixed to a speaker by screws or the like for mounting the mounting device to a speaker. This device can be used to safely mount speakers weighing several hundred pounds and accurately align them.
